» Why do you use glycerin in your toothpastes when recent studies show it demineralizes teeth?
Glycerin is a natural substance derived from vegetable fats that is often used in food, medicines and skincare. It’s well-tolerated by the skin and absorbs in water.  Glycerin is used as a humectant, which means it keeps moisture in the skin. It is also used as an emulsifying agent to help give a formula a smooth consistency for easy application. In our toothpastes, glycerin enhances the brush-ability of the formula and prevents it from drying out. Glycerin does not cause demineralization of the teeth unless it is used in conjunction with bleaching procedures.

» Are you toothpastes certified kosher?
Yes, Weleda toothpastes are certified kosher.

» Are your toothpastes corn free, soy free, gluten free?
In our toothpastes we don’t use raw materials from corn, soy or wheat (gluten).

Ratanhia Mouthwash Concentrate is a refreshing pick-me-up perfect for anytime of the day and is ideal to clean and soothe your teeth and gums.

We recommend using cold water for a refreshing mouthwash and warm water for a sore throat gargle.

» What does RDA mean?
RDA means Radioactive Testing of Dentine Abrasion. The RDA value determines how hard the toothpaste is attacking the dentine during brushing your teeth.

» What is the RDA value breakdown?
Below 40: toothpaste for sensitive teeth
40 - 80: normal toothpaste
50 -150: toothpaste for smokers
Above 200: harmful

» What do the RDA values mean?
The higher the RDA value, the harder the dentine is attacked by the toothpaste. Toothpastes for sensitive teeth usually have an RDA between 30 and 40. This is due to the fact that in the case of sensitive teeth the dentine is often bare at the neck of the tooth. The dentine is much softer than the dental enamel and is therefore attacked too hard at higher RDA values. Toothpastes for smokers usually have a higher RDA value than normal toothpastes. Toothpastes with RDA values above 200 are harmful towards teeth.

» What are the RDA values of Weleda toothpastes?
The Salt Toothpaste has a very low RDA value of 15 due to its primary ingredient bicarbonate. Nevertheless it still has an excellent cleaning effect that even prevents the buildup of tartar.

The Plant Gel Toothpaste with an RDA value of 30 and its mild cleaning effects, which are based on silica, are recommended for sensitive teeth.

The Children's Tooth Gel also contains silica as a cleansing ingredient, which has a slightly higher RDA value of 40. This is because children as a rule are not that persistent in brushing their teeth and are usually not brushing hard enough.

The Calendula Toothpaste and the Ratanhia Toothpaste have an RDA value of 45. The main ingredient is chalk and provides a thorough but mild cleaning of normal teeth.

» Why are your toothpastes free of added fluoride?
We do not add fluoride to our oral care products, as an excessive quantity of fluoride can cause health risks. Fluoride is naturally taken in through mineral water and other sources. Thus, additional quantities are often not needed. However, if extra fluoride is necessary to improve health, we believe this should be determined and prescribed by your health care practitioner.
